    firewire: clean up fw_card reference counting · 459f7923
    Stefan Richter 提交于
    This is a functionally equivalent replacement of the current reference
    counting of struct fw_card instances.  It only converts it to common
    idioms as suggested by Kristian Høgsberg:
      - struct kref replaces atomic_t as the counter.
      - wait_for_completion is used to wait for all card users to complete.
    
    BTW, it may make sense to count card->flush_timer and card->work as
    card users too.
